[R-SIG-Mac]ggobi and Mac OS X

[Jan de Leeuw]

In MacOS X you can build either dynamic libraries (foo.dylib), which are
to be linked against, or bundles (foo.so) which are to be loaded at run
time (plugins, packages). Most ELF based systems dont distinguish the
two.

So in R, for instance, you make libR.dylib and R_gnome.so or tcltk.so.
For dylibs you need the flag -dynamiclib, for bundles you need -bundle
(but more, because you need to tell the linker what to do about 
undefined
symbols). See the configure files for R for more details.

I'll look at ggobi, which I have running, but I am not sure what I 
needed
to do.
